Slightly off Piste!
This is a short Cache & Dash series of mostly simple Caches in mostly traditional hides. Some are a little trickier, the final one is a tad different and is a Diff 3.5. We set the trail as a reason to approach the open bank of the Tamar by a relatively unused route, which includes distant views of Dartmoor, a clear view of Pentillie Castle, and several unusual views of the river as it meanders past Weir Quay, and the Hooe Peninsula. The actual drive takes you firstly down two very quiet remote Cornish lanes, as you approach the original Pentillie Castle gatehouse, then down a fairly busy and fast lane, until the final quiet lane and the start of the old road along the river to Cargreen. You will be able to park alongside all the Caches apart from #11, which lists a parking Waypoint. If possible, time completeing the series to within an hour or so either side of high tide at Cargreen, as the Tamar around Cache #11 will then be relatiely high, and the Millpond there fairly full.
Unfortunately, access to Mount Arrarat woods is verboten, as we would have liked to work our way down to the river here, but as so often, river access and tracks are rarely allowed by private landowners, with public access points few and far between.
